What is the gps coordinate of the center of the Mesh model?

I’m trying to align up the Mesh model and point cloud programmatically.
So, I’m trying to find out the coordinate of the center of the Mesh model as a referencing point in order to shift the mesh model to match with the point cloud location.
How do I get this information? Is it the offset_3d_xyz that returned after the project is created?

PS. as offset_3d_xyz, I’m referring to the returned value from Pix4D API.

You are right. This community post will give more info: What does "offset_3d_xyz" means ?
